l 'rma-INDICATOR.

To all whom it may concern:

Be it known that I, ELBRIDGE I-I. CoRsoN, a citizen of the United States, residing at Boston, in the county of Suiolk and State of Massachusetts, have invented certain new and useful Improvements in Time Indicators, of which the followinvr is a specification, reference being had to the accompanying drawings.

This invention relates to time indicators for regulatin periods of time and for varying the lengt thereof, as may be desired, and has for its object to provide a device of this character to be used in connection with telephones, etc., and more particularly to the long distance telephone where they have the length of conversation limited from three to tive minutes.

Anothenobject is to provide novel means for mounting the indicator on a telephone or nearby so as to be ready for use at any time.

With the above and other objects in View,

i the invention consists in the novel features of construction and opeartion hereinafter fully described, pointed out in the claims and shown in the accompanying drawings, in which*u A Figure 1 eis a front elevation of my improved time indicator mounted for use; Fig. 2 is a side elevation of the same; Fig. 3 is a sectional view taken on the line 3 3 of Fig.

1; Fig. f1 is a similar view taken on the line 41-4 of Fig. 1; and Fig. 5 is a perspective view of a niodiied form of my invention.

Referring more particularly to the drawings 1 indicates the card or support upon which is mounted a tubular element having a contracted intermediate portion 2, and its ends 3 and 3 enlarged to the shape of bulbs to form suitable receptacles for sand or any other suitable material. In the center of the portion 2 is a small opening 41 to allow the sand or other material to readily flow from one end to the other. These bulbs are preferably made of one piece of glass or any other transparent material, but they may 'be made of two or more pieces suitably joined together.

The card upon which the indicator is mounted, may be made of any suitable size and can be constructed of cardboard, wood, metal or any suitable material, and can be used for advertising or any other similar purpose. t

In securing the indicator to the card a hol- Specication of Letters Patent. .Application led November 23, 1910. Serial No. 593,925.

low metal base 5 is provided, said base having an outwardly extending ila-n e 5 and securing points 6 struck out of sai flange to fasten the base securely to the card. Rotatably mounted in the base 5 is a stud 7 having a reduced portion 8 and an enlarged por- -)ion 9 to-hold the stud *securely within the ase.

In securing the indicator to the rotatable stud 7, a clamping member 10. is provided having its ends 12 bent at right angles and a V-shaped recess 13 struck up in the center of the ends 12 and adapted to engage with a raised portion 14 formed in the base 5.

The clamping member 10 is placed on the indicator at 2 so'that the recess 13 in the ends 12 will be placed over the raised por-A tion 14 to keep the indicator in an upright position, and also to keep it from being moved accidentally. The lower part of the member 10 is then brought together and secured to the stud 7 by means of a set screw 15, which securely holds theindicator in an upright position.

InFig. 5 a modified form of my inven- Patented Sept. 5, 1911.

tion is shown which is constructed of a sheet A metal body 16 having a contracted intermediate portion 17, and a glass or any other transparent front 18 for said body. The upper edges of the sides 19 and ends 19 are. provided with a flange 20 to retain thepfront 18 in an upright position. The sides 19 have their central portion brought together at 17 and a small opening 21 .formed therein for sand or any other material or liquid to tow through. In constructing the indicator in this orm and of metal it will allow alcohol or any other liquid to be used instead of sand or any dry material, by running a small air tube from one space to the other, but sand or any other. dry material can be. used in both forms of my invention.

The form of indicator shown in Fig. 5 i

may be secured to the card 1 by the clamping means shown in Figs. 1 and 2 or by any other suitable means.

In using the indicator it is to be placed on or near a telephone, and after a person has been connected up with the one they are to converse with, they turn the indicator until the end containing the sand or other material is on top. When this is done the sand will at once begin to run slowly into the lower end, and when it has all run Jfrom the top end into the lower their time is up, and

if they desire to talk longer they will quickly reverse the indicator and so on until they are through talking. Any amount of sandJ may be placed in the indicator, but it is preferred, in using it on telephones; to have enough sand placed in the indicator so that ,l

it will take from three to five minutes `for the sand to run from one end to the other,

' according to the locality in which the telephone is located.

While I have shown and described the preferred forms of my invention, it will be understood that I do not limit myself to its exact construction but desire to make such `v changes as fairly fall` within the scope thereof. I

It is noted that various changes in the del tails of construction and in the proportions ing any of the features or may be resorted to for successfully carrying the invention into practice without sacrificvdeparting from the scope thereof. Y' s Having thus described my invention what I claim and desire to secure by Letters PatA ent is:--

1. A time indicator comprising a support having a hollow base secured thereto by means of securing points struck out of the 4. flange of the base, a studl rotatably mounted in said base, said stud having anenlarged .portion to hold it within the base, a clamp carrying an indicator bulb secured to'said stud and means for holding said clamps and indicator bulb in an operative position.-

r .2. A time indicator comprising a support having a hollow base plate secured thereto, a stud rotatably mounted in said base plate, said stud having an enlarged portion to hold it within the base', a clamp carryin ,an indicator mounted on the stud, sai clamp having its ends. bent aty right angles and recesses struck up within 'said ends, and raised v,portion formed in said base plate toengage operative position. V

3. A time indicator comprising a support said recesses and hold the indicator in an having a hollow base plate. secured thereto ELBRIDGE H. coRsoN.
